Tungsten-copper (80/20 and 75/25)

Tungsten-copper composites reveal the greatest resistance to arc erosion of all tungsten-based composites. Decisive for the intended purpose is not the composition alone, however, but also the structure (size of grain – distribution of grain) and the structural composition.

Possible applications as resistance welding electrodes and for electro-discharge processing as well as contact material in electronics.

 

Molybdenum

Analogous to its surface appearance, molybdenum is a matt grey to tin-white metal.

It is characterized by a number of excellent physical and mechanical properties such as good resistance at high temperatures under inert gas or vacuum, high heat conductivity, low coefficient of thermal expansion, high elasticity module and good electrical conductivity.

Molybdenum is brittle at room temperature, yet can be formed and worked mechanically more easily than tungsten.

Possible applications as resistance welding electrodes for use in buckling tools, smaller crimpers or for hot-riveting or hot heading. The material is also used as contact material in electronics.

 

Tungsten

Analogous to its surface appearance, tungsten is a matt grey to silvery-white shiny metal.

It has the highest melting point and the lowest vapour pressure of all metals and has good electrical and thermal conductivity. Apart from strongly deformed thin wires or sheets, Tungsten cannot be worked at room temperature.

Possible applications as resistance welding electrodes, for use in welding materials with high conductivity, use in resistance brazing, marking pens, but also as contact material in electronics.
